Cancer and the Cell Cycle Evolution of cells has always been marked by two competing forces: the need for change, so the cell can evolve, and the need to stay the same, so daughter cells can inherit whatever genetic advantage the parent cell had. In the short term, cells work a very long day to make sure their daughter cells are as much like the original as possible. Cell cycle monitors, consisting of many different enzymes, check to make sure that everything is going well each time a cell divides, and if it is not, those monitors stop the cell from dividing until the problem is corrected.

The circular arrow indicates the direction of the cycle. The cell cycle consists of four stages or phases: cell division (M phase, for mitosis); a gap immediately after M phase, called G1; DNA synthesis (S phase); followed by another gap, called G2. The cycle includes three checkpoints: the first is a DNA damage checkpoint that occurs in G1. The monitors check for damage that may have occurred as a result of the last cell cycle or were caused by something in the environment, such as UV radiation or toxic chemicals.

Karyotypes are used to diagnose genetic illnesses and are also used to characterize different forms of cancer. (Courtesy of Diana Dowsley) from histological examinations of cancer cells. These studies showed that most cancer cells have an abnormal karyotype that is characterized by the presence of many broken chromosomes. The Philadelphia chromosome (named after the city where it was first discovered) is a striking example of the relationship between genetic abnormality and cancer induction. This chromosomal abnormality involves a translocation between the long arms of chromosomes 9 and 22.
